Abstract

In a soliton transmission system using lumped amplifiers, pseudo phase matching allows four-wave mixing fields from soliton–soliton collisions to grow uncontrollably and inflict severe penalties. Through numerical simulation, we show that this growth can be eliminated, or at least greatly reduced, through the use of fiber whose dispersion is tapered, either continuously or in steps, in conformity with the fiber loss curve.
